Chii chinonzi inductive sensor?

Mazuva ano otomatiki masisitimu anoshandisa huwandu hwakawanda hwema sensors anosiyana muhunhu uye musimboti wekushanda. Imwe yema sensors akajairika anoshandiswa muminda yakawanda (kusanganisira yeindasitiri yemotokari) ndiyo inductive sensor, uye isu zvino tichaicherekedza zvakanyanya.

Chii chinonzi inductive sensor?

Nehunhu hwayo, iyi sensor ndeyezvinhu zvisiri zvekubata. Mune mamwe mazwi, iyo inductive sensor haifanire kunge iri padhuze nechinhu kuti igone nzvimbo yayo muchadenga.

Induction sensors inowanzo shandiswa kana zvichidikanwa kushanda nesimbi zvinhu nesimbi munzvimbo yakaoma yekushanda.

Iyo inductive sensor inoshanda sei?

Nekuda kwechimiro chemukati, iyo inductive sensor ine mamwe maitiro ekushandisa. Pano jenareta rinokosha rinoshandiswa iro rinogadzira imwe vibration amplitude Kana simbi kana ferromagnetic chinhu chikapinda mumunda wechiitiko cheiyo sensor, iko kudedera kunotanga kuverengerwa nekushandurwa.

Ngatirerukei kuti zvinoshanda sei ...

Kutanga kushanda, iyo sensor inofambiswa, iyo inobatsira mukuumbwa kwemagineti munda. Iyi ndima, zvakare, inogadzira eddy currents iyo inoshandura iyo amplitude yemascillations mune inomhanya jenareta.

Mhedzisiro mhedzisiro yeiyi ese shanduko chiratidzo chekuburitsa icho chinogona kusiyanisa zvichienderana nehurefu pakati peiyo inductive sensor uye chinhu chekuyedza.

Iyo chiratidzo iyo yekutanga inouya kubva kune iyo sensor ndeyeanalog, iyo inoshandurwa kuita logic neakasarudzika chishandiso chinonzi chinokonzeresa.

Ndezvipi zvinhu zveiyo proximity sensor?

Ehezve, kune akawanda marudzi eainopisa maseru, asi iwo akabatanidzwa nekuti iwo ane iwo makuru makuru zvinhu:

Jenareta

Chinhu chakanyanya kukosha murudzi urwu rwechigadzirwa ndiyo jenareta, sezvo ichigadzira munda wemagetsi unobatsira kuona nekuongorora zvinhu zvesimbi uye kuona mamiriro azvo. Pasina jenareta uye munda waanogadzira, kushanda kweiyo inductive sensor kungave kusingaiti.

Chiratidzo chinoshandura

Ichi chinhu chimwe chinhu senge chinokonzeresa, uye basa rayo nderekushandura chiratidzo kuitira kuti sensor igone kudyidzana nezvimwe zvinhu muhurongwa kuti uenderere mberi nekufambisa ruzivo.

Gudzazwi

Chiwedzeredza chinodikanwa kuitira kuti chiratidzo chinogamuchirwa chisvike padanho raunoda rekuenderera mberi nekutapurirana.

Zviratidzo zve LED

Zviratidzo zve LED zvinotarisa mashandiro eiyo sensor uye zvinoratidza kuti iri kana kuti akasiyana masystem ekurwisa ari kuenderera.

Housing

Muviri une zvese zviri pamusoro

Mhando dzema sensors mune emagetsi masystem uye panoshandiswa inductive sensor

Magetsi ekudzora masystem emota dzemazuva ano haafungidzike pasina maseru. Mhando dzakasiyana dze sensors dzinoshandiswa mune angangoita ese masisitimu emota. Iyo mota inoyera tembiricha uye kumanikidza kwemhepo, mafuta, mafuta, kutonhora.

Position uye yekumhanyisa maseru anonamirwa kune akawanda anofamba zvikamu zvemotokari senge crankshaft, muparidzi, throttle, giya shafts, EGR vharuvhu, nezvimwe. Uye zvakare, huwandu hukuru hwema sensors anoshandiswa mune yekuchengetedza mota masystem.

Zvichienderana nechinangwa, mota dzemagetsi dzinoiswa muzvinzvimbo uye nekumhanyisa sensors, mweya inoyerera sensors, emission kudzora, tembiricha, kumanikidza uye nevamwe.

Inductive sensors anoshandiswa zvakanyanya kuyera kumhanya uye chinzvimbo chinotenderera zvikamu, asi zvinoita sekunge kushandiswa kukuru kwerudzi urwu rwechiratidziro kuri kuona kumira uye kumhanya kweinjini crankshaft.

Nekuti masekondi anonyengedza akavimbika kwazvo, kunyanya kana achishanda mumamiriro akaoma, anoshandiswa zvakanyanya kwete chete muindasitiri yemotokari, asiwo mumauto, njanji, nzvimbo uye maindasitiri anorema.

Ndezvipi zvimwe zvatinofanira kuziva nezve inductive sensor?

Iyo inductive nzvimbo uye yekumhanyisa sensor chishandiso chine chayo chaiyo, saka, mukutsanangurwa kwekushanda kwayo, tsanangudzo dzakakosha dzinoshandiswa, senge:

Nzvimbo inoshanda

Iyi nzvimbo inoreva nzvimbo inonongedzerwa zvakanyanya padanho remagineti. Iyo yepakati inowanikwa pamberi penzvimbo inonamira yeiyo sensor uko iko kusunganidzwa kwemagineti munda kwakanyanya.

Zita rekuchinja chinhambwe

Iyi paramende inoonekwa seyefungidziro nekuti haina hanya nehunhu hwekugadzira, tembiricha mamiriro, magetsi, uye zvimwe zvinhu.

Kushanda renji

Iyo yekushandisa renji inoratidza ma parameter anovimbisa anoshanda uye akajairika mashandiro eiyo inductive sensor.

Kururamisa chinhu

Iyo yekugadzirisa chinhu inoenderana neicho chinhu chinogadzirwa nesimbi chinhu, chinotariswa neiyo sensor.

Zvakanakira uye zvakaipira inductive sensors
Kufanana nemamwe marongedzero, ma sensors anonyanyisa ane avo simba uye kusasimba.

Pakati pezvikuru zvakanakira yerudzi urwu rwema sensors ndeaya:

• Zviri nyore kuvaka. Iyo dhizaini yeanopinza sensors iri nyore kwazvo uye haina zvinhu zvakaoma zvinoda kusarudzika kusarudzika. Naizvozvo, sensors vane yakakwira mwero simba uye kuvimbika, kashoma kutyora, uyezve inogona kushandiswa kwenguva yakareba kwazvo.

• · Hunhu hwakakosha - hunhu hwe inductive sensors hunobvumidza iwe kuti uise nyore uye uzvibatanidze kune zvikamu zvemotokari system.

• · Sensitivity - ma sensors emhando iyi anonyatsonzwa, izvo zvinovabvumira kuti vashandise kana vachishanda neakasiyana simbi zvikamu uye zvinhu.

Chinokanganisa chete ndechekuti zvinokwanisika kuti ma sensors anogona kukanganiswa nezvakasiyana zvekunze zvinhu panguva yekushanda, uye nekudaro zvakafanira kupa mamiriro akakodzera asingazokanganisa mashandiro akanaka eanopinza sensors.

Chii chekutarisa kana uchisarudza inductive sensors?

Fomu

Inductive sensors inowanikwa mumhando dzakasiyana-siyana, asi inonyanya kuzivikanwa ndeye cylindrical chimiro chine tambo dzinomhanya kureba kwe sensor. Iyo yakajairwa shinda yekupatsanura tambo ndeye M 5, M 8, M 12, M 18 uye M 30.

Reaction daro

Izvo zvinoenderana neakananga maitiro ejenareta, ayo anokanganisa ne eddy mafungu enzvimbo yakayerwa. Kuwanda kunosiyana kubva ku1 mm. kusvika 25 - 30 mm. zvichienderana nemugadziri.

Sensor mhando

Kazhinji masensa ari analogi (1-10V, 4-20mA) uye digitaalinen. Iyo yekupedzisira, zvakare, yakakamurwa kuva PNP mhando uye NPN mhando. Uye zvakare, zvakakosha kuti uone kana iyo sensor ine yakajairika yakavhurika (NO) kana yakavharwa (NC) yekubuda chinhu.

The waya

Kazhinji tambo-tambo mbiri kana nhatu-tambo tambo inoshandiswa, asi iyo sensor inogona zvakare kuve yakabatana kune inobatanidza.

Mibvunzo nemhinduro:

Ndeapi mashandisirwo emisimboti uye mashandisiro emainductive sensors? Masensa akadaro anoshanda zvichienderana nekushandurwa kweiyo magineti mune coil kana chinhu chesimbi chichipinda munzvimbo yemagneti. Muenzaniso uri mune oscilloscopes, ammeters, kunyange mukushambidza motokari.

Ko induction sensors inoshanda sei? Vanoyera ukuru hwesimba re electromotive re induction. Kana ikozvino inoyerera mucoil ye sensor, uye chinhu chesimbi chinopfuura nayo, inoshandura simba remagineti, uye sensor inoona kuvapo kwechinhu ichi.

Chii chinonzi inductive sensors? High pressure resistant, double waya, all metal, heat resistance, magnetic field resistant, explosion proof, annular, tubular and standard.
